Vertical Cavity surface Emission Lasers (VCSEL) are lasers that emit light from their surface in contrast with regular ???edge emittersâ„¢. Also they have got a vertical cavity , as the name suggests, which enables surface emission.???Vixels??? , as they are commonly called ,have several superior characteristics compared to their edge emitting counter parts.

VCSEL Semiconductor micro laser diodes which emit light perpendicular to their PN junction in a cylindrical beam vertically from the surface of a fabricated wafer and feature circul ....etc

FABRICATION OF VERTICAL AXIS WIND TURBINE


INTRODUCTION
If the efficiency of a wind turbine is increased, then more power can be generated thus decreasing the need for expensive power generators that cause pollution. This would also reduce the cost of power for the common people. The wind is literally there for the taking and doesn't cost any money. Power can be generated and stored by a wind turbine with little or no pollution. If the efficiency of the common wind turbine is improved and widespread, the common people c ....etc

Vertical Take “ off and Landing
INTRODUCTION
Twenty years after ever jet flight took place, vertical takeoff and landing (VTOL) emerged as a concept, which was soon to be successfully implemented. Dr A.A Griffith, in 1941 who was then the chief engineer of Rolls Royce ltd. put forward this idea in his paper to the aeronautical research council. He proposed the idea of using small lift engines for lift only and not for normal flight. He claimed that there was great advantage in using a wing configuration and prop ....etc

In an information society, where the primary preoccupation in life is the generation, dissemination and management of information, there is an ever-increasing appetite for computing power and interconnection bandwidth. In the coming era of teraflop computing and multi terabyte storage, multiple processors and large data stores will be interconnected with up to terabit per second aggregate bandwidth over distance extending from just centimeters to hundreds of meters. VCSEL based optical interconnections can meet the speed, distance and density d ....etc

The vertical-cavity surface-emitting laser (VCSEL) is a type of semiconductor laser diode with laser beam emission perpendicular from the top surface, contrary to conventional edge-emitting semiconductor lasers (also in-plane lasers) which emit from surfaces formed by cleaving the individual chip out of a wafer.There are several advantages to producing VCSELs when compared with the production process of edge-emitting lasers. Edge-emitters cannot be tested until the end of the production process. If the edge-emitter does not work, whether due to ....etc

A Study of Vertical Axis Wind Turbines



Introduction:

As we all know, the demand for energy is increasing exponentially as more and more people inhabit this earth. At the same time, the energy source that met all of our needs in the past decades, non-renewable in nature, seems to decrease in equal pace leaving us at the door steps of renewable energy sources for help as we go forward in our journey in to the future. Due to this inevitable need, many scientists and researchers are turning back to the essent ....etc
